Physics Creative Thinking Measurement using Two-Tier Multiple Choice to Support Science, Technology, Engineering, and Mathematics

Abstract

The Importance of STEM as an implementation to Indonesian Curriculum has to be backed with proper assessment. This due to assessment take the most important part in evaluation. This research develops creative thinking assessment, which using 3 stages including test design, trials, and assembling. The design of the test will be tested in two-tier multiple choice and scored using item response theory (IRT) with daily problem in Physics. The answer will be varied in divergent answer, consisting of fluency, flexible, original and elaborate idea as a creative thinking aspect. From 5 expert's judgements, the test passed with 7.2 value using Aiken's V index. After revised, the test was reach trial stage with 270 students in several schools in Gunung Kidul. The Reliability of the test described in information function and SEM (Standard error measurement) are valid result and fit to PCM. The test is ready to assemble since its valid and reliable.
